The G7c Multi-Gas Pump Detector offers full control over confined space entries and gas leak inspections, combining intelligent design with real-time connectivity to enhance safety and efficiency.

Description

It features a built-in pump capable of drawing samples from up to 30 metres (100 feet) away, allowing for easy pre-entry checks and leak detection. Users can switch between pump and diffusion modes to adapt to changing environments, while cellular and satellite connectivity ensures consistent communication without the need for Wi-Fi or mesh networks. GPS tracking allows you to monitor worker locations or locate misplaced devices. Enhanced safety alerts automatically respond to incidents like falls, no-motion events, and missed check-ins.

The G7c also supports optional two-way voice or push-to-talk communication (cellular version), and provides accurate gas detection through broad-spectrum, poison-immune sensors. Interchangeable, pre-calibrated cartridges minimise downtime, and real-time data is accessible through Blackline Live and Blackline Analytics for continuous monitoring and reporting.

Unlike traditional gas detectors, the G7 multi-gas pump connects directly to cloud-hosted data without the hassle of managing Wi-Fi or mesh networks. This ensures uninterrupted communication and full visibility of safety operations.

You can also customise workflows to suit your needs—turning the pump on and off as required.

When preparing for confined space entry, select ‘pre-entry’ mode to activate the internal pump. This feature automates gas sampling, guiding users on the correct waiting time based on tubing length. Instead of relying on assumptions, workers can proceed with confidence, knowing the space has been properly tested.

The G7 multi-gas pump is built to last, with a two-or three-year warranty on hardware and sensors, plus the option for an extended warranty. With its robust design and cutting-edge technology, it’s the ultimate tool for ensuring worker safety in confined spaces.

FAQs
How long does calibration or bump test take?

Calibrations take about four minutes, while bump tests take around 30 seconds. The exact time may differ depending on the gas being used.

How do I change which gas(es) G7 detects?

G7’s cartridge can be changed by removing the two screws on either side of the cartridge and pulling upward. To add a new cartridge, slide the cartridge onto G7 and replace the screws. If you wish to order new gas cartridges, please contact Rockall Safety.

Will windy conditions affect the accuracy of gas readings when using the multi-gas pump cartridge?

When operating the multi-gas pump cartridge it is best practise to shield the sensors from a windy environment to ensure the most accurate gas measurements. When conditions make it difficult to protect the G7’s sensors from the wind, the multi-gas calibration cap can be used as a shield.
